Specifically, as shown in fig. 3 to 5, at least one of the housing 10, the first cover 30 and the second cover 40 is snap-fitted to the frame 20.

Specifically, as shown in fig. 6 to 8, the inflation mechanism 50 includes a cylinder 51, a piston body 52, a connecting rod 53, and a driving assembly 54.

The cylinder 51 has an air chamber 511 extending along a first predetermined direction AA, and the air chamber 511 is a hollow area inside the cylinder 51.

The piston body 52 is located in the air chamber 511 of the cylinder 51, the piston body 52 includes a first piston 521, the peripheral side of the first piston 521 abuts against the inner wall of the cylinder 51, and the first piston 521 reciprocates in the air chamber 511 of the cylinder 51 in a first predetermined direction AA to compress air in the air chamber 511. The first piston 521 has a connecting surface 521a, and the connecting surface 521a is a surface of the first piston 521 connected to the connecting rod 53.

The connecting rod 53 is used as a component of the inflation mechanism 50 for driving the piston body 52 to reciprocate in the air chamber 511 of the cylinder 51, the connecting rod 53 is fixedly connected to the connecting surface 521a of the first piston 521, the extending direction of the connecting rod 53 forms a first included angle with the connecting surface 521a, the first included angle is an acute angle or an obtuse angle, that is, the connecting rod 53 is connected to the first piston 521 in an inclined manner, or the extending direction of the connecting rod 53 is not perpendicular to the connecting surface 521a of the first piston 521.

The driving assembly 54 is connected to one end of the connecting rod 53, which is far away from the piston body 52, the driving assembly 54 is configured to drive the connecting rod 53 to swing so as to drive the piston body 52 to reciprocate along the first preset direction AA, that is, the driving assembly 54 is connected to the connecting rod 53 so as to drive the connecting rod 53 to swing, the connecting rod 53 is connected to the first piston 521 so as to transmit power to the first piston 521, and thus the piston body 52 is driven to reciprocate along the first preset direction AA.

When the connecting rod 53 swings until the extending direction of the connecting rod 53 is the same as the first preset direction AA, a second included angle (β shown in fig. 7 and 9) is formed between the connecting surface 521a of the first piston 521 and the plane S perpendicular to the first preset direction AA, and it can be understood that the connecting rod 53 forms a regular swinging track under the action of the driving assembly 54, so as to drive the piston body 52 to perform regular reciprocating motion in the cylinder 51 along the first preset direction AA, so that the piston body 52 has a corresponding position in the cylinder 51 when the connecting rod 53 swings to a position, and when the piston body 52 is at different positions, the size of the second included angle formed between the connecting surface 521a of the first piston 521 and the plane S perpendicular to the first preset direction AA is also different.

It should be noted that the frequency of reciprocation of the piston body 52 within the cylinder determines the operating efficiency of the charge pump. In this application, the connecting rod 53 is fixedly connected to the connecting surface 521a of the first piston 521, so that the connecting rod 53 and the first piston 521 form a whole, a first included angle is formed between the extending direction of the connecting rod 53 and the connecting surface 521a, so that the connecting rod 53 is obliquely connected to the connecting surface 521a of the first piston 521, and by the design of the formed first included angle, the problem that the included angle between the connecting surface 521a of the first piston 521 and the horizontal line is too large due to the eccentric movement of the connecting rod 53 can be reduced in the process that the connecting rod 53 pushes the piston body 52 to move in the cylinder 51 along the first preset direction AA, so that the included angle between the piston body 52 and the horizontal line is reduced, and the working efficiency of the inflation mechanism 50 is improved.

In some embodiments, with continued reference to fig. 6 to 8, the inflation mechanism 50 further includes at least two reinforcing portions 55, the reinforcing portion 55 is connected to an end of the link 53 close to the connecting surface 521a, an end of the reinforcing portion 55 far from the link 53 is connected to the connecting surface 521a, and an extending direction of the reinforcing portion 55 intersects with an extending direction of the link 53.

Specifically, the number of the reinforcing portions 55 is two, and the two reinforcing portions 55 extend in opposite directions and form a "Y-like" structure with the link 53. In this design, the number of points of force applied between the connecting rod 53 and the first piston 521 is increased by the design of the at least two reinforcing portions 55, so that the force applied to the first piston 521 by the connecting rod 53 can be dispersed into a plurality of components acting on the first piston 521 in the extending direction of the reinforcing portions 55, thereby enhancing the structural strength of the joint between the connecting rod 53 and the first piston 521 and prolonging the service life of the inflation mechanism 50.

Further, the first included angle is an acute angle α, and a value range of α satisfies a conditional expression: alpha is more than or equal to 77 degrees and less than or equal to 87 degrees, for example, the value of alpha can be 77 degrees, 82 degrees or 87 degrees, etc. The value of α may preferably be 79 degrees. When the value of the first included angle exceeds the lower limit of the conditional expression, the circumferential side of the first piston 521 and the inner wall of the cylinder 51 can realize good sealing, but the inclination angle between the connecting rod 53 and the first piston 521 is small, which is not beneficial to improving the frequency of the reciprocating motion of the piston body 52 in the cylinder 51, which is not beneficial to improving the working efficiency of the inflation mechanism 50, and when the value of the first included angle exceeds the upper limit of the conditional expression, which is beneficial to improving the frequency of the reciprocating motion of the piston body 52 in the cylinder 51, which is beneficial to improving the working efficiency of the inflation mechanism 50, but the inclination angle between the connecting rod 53 and the first piston 521 is large, it is not favorable for the sealing between the peripheral side of the first piston 521 and the inner wall of the cylinder 51 during the movement of the piston body 52.

With continued reference to fig. 6 to 8, in consideration of machining errors in actual production, the first included angle formed by the extending direction of the connecting rod 53 and the connecting surface 521a of the first piston 521 is designed such that during the movement of the piston body 52 in the cylinder 51, there may be a gap between the peripheral side of the first piston 521 and the inner wall of the cylinder 51, thereby causing the sealing performance of the inflation mechanism 50 to fail.

It is further designed that the piston body 52 further includes a second piston 522, the second piston 522 is connected to a side of the first piston 521 away from the connecting rod 53, and during the movement of the piston body 52 along the first preset direction AA, a peripheral side of the second piston 522 is at least partially spaced from the inner wall of the cylinder 51, that is, during the movement of the piston body 52 along the first preset direction AA, the peripheral side of the second piston 522 may be completely spaced from the inner wall of the cylinder 51, and a portion of the peripheral side of the second piston 522 may be spaced from the inner wall of the cylinder 51, and another portion of the peripheral side abuts against the inner wall of the cylinder 51.
